Check if you have 24volt out of the board if not replace it.

We have enjoyed a Rheem Thermostat and a Paloma Eco Sense tankless gas water heater #RTG-74XN-2 for 2 and 1/2 years, but now there are error codes flashing and resetting the thermostat doesn't hold. ...


Before calling service technician, open following links for Rheem troubleshooting resources, including generic error codes and contact information for Rheem and recent manuals:
http://waterheatertimer.org/Troubleshoot-Rheem-Tankless-water-heater.html
http://www.fixya.com/tags/rtg_74pvn

Error codes are start place for troubleshoot, and multiple error codes can indicate bad PC board.
Same error code on one machine can be different cause and solution than another machine.

Error 76 is usually communication problem with remote control.
Disconnect wires from machine, and clean terminals is a start point.
Wire between machine and remote might be bad, or remote control is bad, or PC board or wiring connections are bad.

The problem might be solved by having technician catch the machine up on yearly maintenance.

Manual for same-similar product shows maintenance and troubleshooting and a few error codes, but not 76:
For the most part, the manual recommends calling service technician instead of offering DIY details.

I have a Kenmore dishwasher 66517033400 that has a flashing green clean light. The light is flashing 7 times per cycle.


This information may help in your situation. The following link explains how you may be able to clear the blinking clean light problem:

http://www.fixya.com/support/r417123-blinking_clean_light_kenmore_whirlpool

Now, keep in mind all dish washers are not alike and have different panel options. If you do not have the same set up that I have mentioned, the tech sheet for your dishwasher will explain the touch pad functions. The tech sheet is located behind the lower toe panel under the door and lists the proper sequence of buttons to push for diagnostics and troubleshooting.

NOTE: Sometimes the tech sheet is located behind the inner door panel. You will need to remove the screws securing the inner panel to access it if this is the case. Make sure you turn off the main power breaker before doing so.

Sometimes this can be a momentary glitch in operation. However, if the problem keeps reoccuring the number of flashes is an indication of which circuit is causing your problem. Again, refer to your tech sheet to determine this.

If you have any questions, please let me know. I hope this helps you solve your problem.

Mod# A-SMH18SA SER# 2791206189 Heat controller mini-split. Cust says lights flashing on board- he resets it, yet it resumes to just flashing at the board. Nothing runs. Long drive out there- any ideas. Was...


First of all, Heat Controller does not mount any schematics on their systems panels at all and supply no information for the service tech to code the light on the outdoor board. This is unbelievable.
Anyway- I found that the electrician had re-arranged breakers in the panel supplying the building and had connected the outdoor heat pump to 120v instead of 240v. He had interpenetrated the connection at the unit that has marked 2(N) as being a neutral connection. I explained that on 120v systems, that is neutral, but on a 240v system, it's L2. The outdoor board was flashing 5 times after the power was turned on for 3 minutes. Voltage at "S" was 38.4v, with this condition and the indoor units lights (all) were flashing every second and beeping as well.
It's running fine now that we are connected to the proper voltage.
